KARL KGSZEGI, OF BAJA, AUSTRIA-HUNGARY.

ELASTIC WHEEL.

To all whom it may concern Be it known that I, KARL Kosznor, a subject of the King of Hungary, and resident of Baja, Austria-Hungary, have invented certain new and useful Improvements in Elastic \Vheels, of which the following is a description.

The present invention relates to that type of wheel for vehicles of any description in which a series of springs are arranged between the axis and the wheel rim.

According to the present invention, great resiliency of the wheel is attained by cmploying two equilateral triangles the sides of which are formed of flat springs, the said triangles being superposed so that the angles of both triangles lie equidistant in the circle formed by the rim of the wheel. A drum is advantageously fixed to the axle and fits within the hexagonal figure formed by the two superposed triangles, while the sides of the latter are supported at their points of intersection by a series of rolls mounted between flanges which may be formed on the said drum. Thus, the axle is supported in the rim of the wheel between two triangular sets of springs. The resiliency of the wheel may be increased by inclosing the two spring triangles within a spring polygon such as a hexagonal figure, the sides of which are formed by flat springs which in their turn may be linked to the centers of the sides of a second hexagonal spring frame, the ends of the sides of which are linked to the interior of the wheel rim. Instead of a drum bearing against the inner sides of the two triangles a second set of rolls may be employed which may be supported between the same flanges as the outer set.

In order to render the specification easily intelligible reference is had to the aocom panying drawings in which similar numerals of reference denote similar parts tl'iroughout the several views.

Figure 1 is a side elevation partly in sec tion of one embodiment of the present invention, and Fig. 2 is a central horizontal section through the same, Fig. 3 shows a modified form of linking the ends of the springs to the rim, Fig. 4 shows a modified form of the invention in which the triangles are surrounded by hexagonal spring frames, Figs. 5, 6 and 7 show other modifications of the invention.

Referring first to Figs. 1 and 2, the sides 1, of the two triangles consist of flat springs Specification of Letters Patent.

linked to the rim 2 of the wheel at S, 8, the arm or web 9 being provided between the two links 8 to limit their play. To the axle t keyed or otherwise attached a drum 3 having extending flanges between which rolls 5, 5 are mounted. The periphery G of this drum 3, bea rs against the inner sides of the hexagonal frame forn'led by the two siu ierposed triangles while the rolls 5 lie one each in the exterior angles formed be tween the points of attaclnnent oi the ends of the triangle sides to the rim.

From the above description it will be evident that a very etl'ectivc spring wheel is attained, the axle of which is yieldingly supported in every radial direction.

In Fig. 3 a bell crank lever 8 pivot ally supported at 10 in a bearing 11. attached to the inner surface of the rim and the ends of the springs 1 are linked to the ends of the said bell. crank lever which allows them a certain amount of play.

in the modification shown in Fig. 4; the angles of the triangles are supported in bearings 13 mounted at centers of the sides of a surrouiuling hexagonal spring frame 12, while the corners of the latter :l'rame are linked at 8* to the centers of the sides of a second surrounding hexagonal frame 12 the corners oil" which are again linked at 8 to the wheel rim 2. In this modification the resiliency of the wheel is considerably increased.

.ln the niodilieation shown in Fig. 5 a second set of rolls 7 is eniployed in place of the drum 6 to support the interior of the sides of the triangles, while in Fig. (3 corner rolls 5 are arranged inside the triangles while the rolls 7 are arranged outside the same.

In Fig. 7 the exterior set of rolls are arranged opposite to the interior set 5* thus supporting the two triangles at both sides of their points of intersection. The spring frames may, of course, be polygonal in term, the invention not being restricted to the employment of triangular and hexagonal frames as will be readily understood.

I claim as my invention 1. In a resilient wheel the eombimition of a series of llat springs in the form of polygons lying in different planes between the rim and the axle, links connecting the corners of the polygons to the wheel rim, means carried on the axle to support, loosely sliding, without connection the sides of the said polygonal springs and a series of rolls supported on the axle to engage loosely sliding, without connection the outer angles formed at the points of crossing of the sides of the various polygons.

2. In a resilient wheel, the combination of a pair of trlangles, the sides of whlch are formed of fiat springs, said triangles lying in different planes and having their bases at opposite sides of the axle, a drum on the axle to engage loosely sliding, without connection nection in the exterior angles formed at the point of crossing of the sides of the two triangles. a

3. In a resilient wheel, the combination of a pair or" triangles, the sides of which are formed of fiat springs, said triangles lying in different planes and having their bases at opposite sides of the axle, a drum on the axle to engage loosely sliding, without connection the inner sides of both triangles, a series of rolls supported on the drum to engage loosely sliding, without connection in the exterior angles formed at the points of crossing of the sides of the two triangles, and a series of spring hexagonals inserted between the triangles and the rim, the points of the triangles being hinged to the sides of the inner hexagonal and the points of the latter to the sides of the outer hexagonal and the points of the latter hinged to the rim.

4. In a resilient wheel the combination of a series of flat springs in the form of polygons lying in different planes between the rim and the axle, links connecting the corners of the polygons to the wheel rim, means carried on the axle to support loosely sliding, without connection the sides of the said polygonal springs and a series of rolls supported on the axle to engage loosely slide ing, without connection the angles formed at the points of crossing of the sides of the various polygons. V In testimony whereof I aflix my. signature in the presence of two witnesses.
